Cannot read property 'uploadFinish' of undefined

[joaocosta-azores]

I keep getting this error "Uncaught TypeError: Cannot read property 'uploadFinish' of undefined"

I use codeigniter and i've incorporated dialog.htm as views. The upload is done succesfully, image is uploaded to correct folder and i get "Result: file_uploaded", but image is not embed into tinymce because if this error.

               window.parent.window.jbImagesDialog.uploadFinish({
        		filename:'assets/upload/justboil.me/ca40e714dbb8ee23cc90d8cb90c6b270.png',
        		result: 'file_uploaded',
        		resultCode: 'ok'
        	});

It seems like it can't get jbImagesDialog object on parent.window
